The surface area of the hemisphere with radius r = 19 cm. is 3400.62 square centimeters
<h3>How to determine the surface area?</h3>
The radius is given as:
r = 19
The surface area of a hemisphere is:
Area = 3πr²
So, we have:
Area = 3 * 3.14 * 19²
Evaluate
Area = 3400.62
Hence, the surface area of the hemisphere is 3400.62 square centimeters
